Answer: C (I don't see answers for B nor E)
Step-by-step explanation:
Answer:
16. A
17. D
Step-by-step explanation:
16. By saying that a line intersects one plane and then another, you are saying that a line is existing on two planes. This is a direct contradiction to the statement.
17. The triangle is equilateral because syllogism is basically connecting the dots. If the angles in the triangle are all equal, it has all equal sides, and if it has all equal sides, then it is equilateral, therefore, it is D, not C.
The answer is 50/100 same as the decimal sort of
Answer:
-19 ½
Step-by-step explanation:
6 × -3 = -18
½ × -3 = -1 ½
-18 + -1 ½ = -19 ½
Answer: 77 and 103
Step-by-step explanation:
\frac{\sin A}{a}=\frac{\sin B}{b}
a
sinA
=
b
sinB
From the reference sheet (reciprocal version).
\frac{\sin G}{960}=\frac{\sin 69}{920}
960
sinG
=
920
sin69
Plug in values.
\sin G=\frac{960\sin 69}{920}\approx 0.9741709
sinG=
920
960sin69
≈0.9741709
Evaluate.
G=\sin^{-1}(0.9741709)\approx 76.95\approx 77^{\circ}
G=sin
−1
(0.9741709)≈76.95≈77
∘
Inverse sine and round.
\text{Quadrant II: } 180-77=103^{\circ}
Quadrant II: 180−77=103
∘
Sine is positive in quadrants 1 and 2.
\text{Check for possibility:}
Check for possibility:
No triangle's angles may add to more than 180.
69+77=146^{\circ}\leftarrow \text{Possible}
69+77=146
∘
←Possible
Less than 180.
69+103=172^{\circ}\leftarrow \text{Possible}
69+103=172
